It updates you speedo cluster to the latest version with enabled eco mode and shift light. I'm guessing you have a facelift as It's only compatible with the facelift.
Your mpg figures will be a bit off for a few weeks as the car has to relearn your driving style.

yeah I have a 59 plate faceliftall sorted and updated.did crap myself tho because it failed the 1st time and my complete cluster wasn't working but did it again and it completed in 19 mindid turn the laptop screen off half way through for 5 min or so.

Hi, I have a modified ELM327 device that I've successfully modified my 2011 Focus ST, auto lock, seat belt reminder alarm, etc.
So I decided to try it on my C-Max (58 plate). Well, it will read the GEM info and that’s about it. Can't get the VIN or anything else to work, read configuration. Just get errors. Any ideas welcome, tried a couple of times, Focus ST is fine, same laptop & software ELMConfig 0.2.3, same configuration.
Thanks
